After a season of bad harvests, the woodcutting king [Olof Ingjaldsson] was sacrificed to Odin so that his people might have good crops. He was succeeded by his son Halfdan Whiteleg, who is said to have extended his rule over much of southern Norway. Halfdan died at a ripe old age, was dully placed in a burial mound, and his deeds were sun by the bards.
